Audio processor for object-dependent processing

AbstractWO15011026A1 [EN] An audio processor, wherein the audio processor (10) comprising an input interface (12) for receiving at least one input audio channels (14) a detector interface (16) for receiving a detection signal (18) indicating an information (34) on an object (20) interacting with sound (22) emitted by at least one loudspeaker (24). Further the audio processor comprising a sound modifier (26) for modifying the at least one input audio channel (14) depending on the detection signal (18) such that an influence of the object (20) on a sound impression of a listener (28) is reduced or eliminated, to obtain at least one modified channel (30) and an output interface (32) for outputting the at least one modified channel (30) to the at least one loudspeaker (24).
